Design & Reporting Criteria for Reed Bed & Fen
DESIGN AND REPORTING CRITERIA FOR REED BED AND FEN RESTORATION IN MINERAL WORKINGS 1 R Neil Humphries and Roger Meade 2 Abstract. Hanson Quarry Products Europe and the statutory nature conservation body for England, English Nature (now Natural England), have a Partnership Agreement whereby Hanson in 2002 became the UK Habitats Champion for reed bed and fen recovery. Both reed bed and fen habitats are identified as a priority to halt their recent decline and to be enhanced and expanded in the UK Biodiversity Action Plan (BAP). The mineral extraction industry can significantly contribute to the 2010 national recovery targets. In 2003 English Nature commissioned, and subsequently published in 2007, 'Design & Reporting Criteria' to guide and facilitate the successful creation of reed bed, other swamp and fen vegetation as an after use of mineral extraction sites, and their subsequent reporting for inclusion in the national UK and local Habitat BAP inventories and audits. Reed bed is a specific type of open-water transition fen dominated by the common reed Phragmites australis and fen a generic term for this and other wetland types influenced by water that has been in contact with rock or soil. The term 'fen' embraces a very wide range of vegetation composition from low sedge and moss dominated to tall reed and tall-herb swamp types, and grading into the ‘wet’ end of meadows and woodland types. The scope for the creation of the various types of fen is dependent on a number of key physical factors (climate, hydrology, substrate (soils and geology) and fertility), but also in practice, land management and the availability of plant material.

Removal of Salinity Using Interaction Mangrove Plants and Bacteria in Batch Reed Bed System Reactor
Journal of Ecological Engineering Received: 2018.10.30 Revised: 2018.12.01 Volume 20, Issue 4, April 2019, pages 84–93 Accepted: 2019.02.16 Available online: 2019.02.27 https://doi.org/10.12911/22998993/102792 Removal of Salinity using Interaction Mangrove Plants and Bacteria in Batch Reed Bed System Reactor Rachmi Layina Chimayati1*, Harmin Sulistiyaning Titah1 1 Department of Environmental Engineering, Faculty of Civil, Environmental and Geo Engineering, Institut Teknologi Sepuluh Nopember, Keputih, Sukolilo, 60111 Surabaya, Indonesia * Corresponding author’s e-mail: [email protected] ABSTRACT The current method of seawater bio-desalination can effectively provide freshwater. This method works by sepa- rating the salt contained in water into clean water with a lower salinity. In this study, the researchers conducted an experiment of the bio-desalination method by combining mangrove plant and Vibrio alginolyticus bacteria as well as the presence of a filter layer component composed of sand and gravel in red beed system reactor. The concept of phytotechnology was to utilize plants as environmental technology capable of solving environmental problems. In contrast, the term phytoremediation was used to denote the process of plants absorb, take, change and release con- taminants from one medium to another. The purpose of this study was to determine the reduction of salinity on the mangrove plant Rhizophora mucronata (Rm) and Avicennia marina (Am) with the addition of Vibrio alginolyticus (Va) bacteria in the bio-desalination process using a reed bed system. This study combines plants and bacteria for artificial saline desalination processes. The compounds contained in plants are absorbed in the form of cations or anions, while the addition of the bacteria was carried out to support the process of salt absorption in plants.

Diversity, Current Knowledge and the Significance of the Flora of Tasek Bera Ramsar Site, Pahang, Malaysia
Journal of Wildlife and Parks (2014) 27 : 111-120 111 DIVERSITY, CURRENT KNOWLEDGE AND THE SIGNIFICANCE OF THE FLORA OF TASEK BERA RAMSAR SITE, PAHANG, MALAYSIA Rafidah, A.R.*, Chew, M.Y., Ummul-Nazrah, A.R. & Kamarudin, S. Flora Biodiversity Program, Forest Biodiversity Division, Forest Research Institute Malaysia (FRIM) *Corresponding author: [email protected] ABSTRACT Tasek Bera — the largest natural freshwater lake in Peninsular Malaysia is made up of a mosaic of micro-habitats and flora communities, including open water, rassau swamp, Lepironia reed-bed, seasonal freshwater swamp forest and the surrounding lowland dipterocarp forest. Botanical collecting and transect studies on the various habitats were carried out in 2007 to 2009, the last was part of the Biodiversity Inventory of Ramsar Site, in both the wet and dry seasons. The aquatic or swampy habitats covered were Lubuk Gah Bahau, Lubuk Hantu Tinggi, Lubuk Kuin, Lubuk Luon, Lubuk Pa Arit, Lubuk Ranting Patah, Lubuk Regeh, Lubuk Sangla Besar, Lubuk Sangla Kecil, Sungai Bera and Sungai Tasik; while forested habitats surveyed were Batin Md. Nor (Penchok) Camp, FELDA Bera 3 and 5, Kampung Gegereh, Kampung Jelawat, Kampung Pathir, Mekok Camp, Pos Iskandar, Pulau Jelai, Taman Herba and Tanjung Kuin. Previous surveys had recorded 52 species of vascular plants from the open water, rassau swamp and lowland dipterocarp forest habitats visited, representing a mere 6% of the total 807 species from 400 genera and 128 families, now known to occur in Tasek Bera. Satellite imagery records that 67% of Tasek Bera consists of freshwater swamp forest. However, this habitat type is still the least known despite numerous field surveys, due to logistic difficulties in accessing these boggy swamps sandwiched between tall rassau thickets and lowland dipterocarp forest.

It presents the plant encroachment process and its environmental and economic consequences based on the example of selected lakes of the Wielkopolska Lakeland. In order to estimate changes of quantity in the riparian vegetation structure, historical records of changes of reed bed areas were compared with their present areas. Historical data included bathymetric plans from the 1960’s created by the Institute of Inland Fisheries and information obtained from interviews with the inhabitants of settlements located in the vicinity of the studied lakes. Present-day boundaries of reed bed zones were identified using orthophotos, aerial photographs and in situ inspections. In the course of the field research, identification of plant species and estimates of plant condition in the studied stands were carried out. Obtained data combined with data on local hydrological-meteorological conditions, water quality and land use in the direct vicinity of lakes allowed the authors to determine the conditioning factors of riparian vegetation encroachment.

What are wetlands? There are many different types of wetlands, including ponds, rivers, lakes, mangrove forests, swamps, bogs and fens. Fens (which get their water from different sources) and bogs (which only receive water from rainfall) are both peatlands, whereas marshes and swamps (forested marshes) are mineral soil-based wetlands. A common feature of all of these habitats is that they form a boundary between truly terrestrial (land) and truly aquatic (or marine) environments. Wetlands are generally divided into two types: coastal, which are saline, and inland, freshwater wetlands. Wetlands provide a significant number of valuable ecosystem services for people, including: • Provision of food (e.g. fish and rice) and building materials (e.g. timber from willow and mangroves) • Flood protection • Carbon sequestration • Water purification • Tourism and leisure opportunities • Fisheries support • Storm protection What are wetlands continued... Ecosystem services are functions of natural habitats that are useful for humans, which also include services such as pollination and the production of oxygen by photosynthetic organisms. Ecosystem services are often assigned an economic value to try to ensure that the loss of natural ecosystems is not disregarded in financial planning, providing an incentive for their protection.

Journal of Ecological Engineering Received: 2020.03.11 Revised: 2020.05.30 Volume 21, Issue 6, August 2020, pages 212–223 Accepted: 2020.06.15 Available online: 2020.07.01 https://doi.org/10.12911/22998993/124075 The Removal of Salinity in a Reed Bed System Using Mangroves and Bacteria in a Continuous Flow Series Reactor Tri Cahyo Puspaningrum1*, Harmin Sulistiyaning Titah1 1 Department of Environmental Engineering, Faculty of Civil, Planning and Geo Engineering, Institut Teknologi Sepuluh Nopember, Keputih, Sukolilo, 60111 Surabaya, Indonesia * Corresponding author’s e-mail: [email protected] ABSTRACT The supply of clean water is a major environmental problem in some areas, which is possibly handled through the biodesalination technologies, a concept that involves separating the salt content, and reducing salinity, using bacteria and plants. This research therefore applied Avicennia marina (AM) and Rhizophora mucronata (RM) mangroves, in addition to Vibrio alginolyticus, in 12 reactor reed bed systems arranged in series (AM-RM) to attain a continuous flow. The evaluated salinity level was 20‰ and 25‰, obtained using artificial saline water. Meanwhile, the reed bed system, measuring 0.14 m3 (0.7×0.5×0.4 m), comprises a filter layer component, which consists of sand and gravel, with a diameter of 1 cm and 2 cm. This investigation was performed for 18 days, and samples were collected every 2 days, and the main parameters of salinity, Na, Cl and the potassium ion concentra- tion, electric conductivity and Colony Forming Unit (CFU), as well as the supporting parameters, including pH and temperature, were evaluated. The results showed a water discharge rate of 18 mL/min, and the addition of Vibrio alginolyticus, produced the best salinity level (90%) on day 6 of operation.
